4E Error Code Samsung Washer

The 4E error code is a common problem that many Samsung appliance owners have faced at least once. It could indicate a problem with the water supply or the drain system. However, pinpointing the exact cause can be tricky, especially if you’ve never dealt with such a problem before.

In this guide, we’ll help you understand what’s causing the 4E error code on your Samsung washer and how to fix it, so stick around.

How to Fix the 4E Error Code on a Samsung Washing Machine

There are several possible reasons why your Samsung washing machine is displaying a 4E error code. Now, let’s walk you through all of these problems and guide you on how to deal with each of them in the following sections:

Bent Drain Hose

First, you need to make sure that there are no bends or kinks in the water hose. If there’s a problem with the water supply, it’s probably due to ample water flow rate or low water pressure, both directly resulting from a bent hose. As a general rule of thumb, the water pressure should be anywhere from 0.5 bar all the way up to 8 bar.

Just make sure that you power off the washing machine before inspecting the hose. You might also need to pull the washing machine away from the wall a bit to access the drain hose from behind.

Other things you need to check in your washer’s drain hose include:

  • The hose must be inserted 6 inches or less into the sink
  • The hose is adequately secured
  • The height of the hose is at least 18 inches and 96 inches at most
  • The hose shouldn’t have a drain hose extension attached to it (These are unreliable and will cause problems to your appliance)

Clogged Water Hose Mesh Filter

Clogged Water Hose Mesh Filter

A clogged water hose mesh filter may cause your washer to display the 4E error code. In that case, you need to check whether anything is clogging the hose by doing the following:

  • Cut off the water supply to the washing machine
  • Uninstall the hose from the rear part of the appliance
  • Use pliers to remove the filter from the hose
  • Rinse the mesh filter thoroughly until there are no signs of debris or dirt on it
  • Reinstall the filter in its respective location
  • Double-check that all the connections are adequately secured
  • Turn on the water tap
  • Turn off the washing machine and then on again

Problems With the Water Supply

Another possible reason for the 4E code is a damaged water supply system. Before repairing or replacing any components, make sure that your water supply is supplying water into both entry points, which include one hot entry and one cold entry. It’s worth noting that you must ensure adequate water flow to both of them, even if you only use cold or hot water.

If you’re sure that water is reaching the two entry points, proceed with the next diagnostics.

Bent Supply Pipes

Bent Supply Pipes

Inspect the supply pipes and make sure that none of them is leaking, bent, or kinked. One common reason for a bent pipe is that the washing machine is too close to the wall. Try to move the washer off the wall a little bit and look at the supply pipes.

Supply Hose Blockage

If your water supply valves and pipes are intact, but you still get the 4E code, chances are there’s something that’s blocking the supply hose from the inside. First, remove the water hose, then fill it from one end and see if the water passes unobstructed from the other end.

If you suspect that the water isn’t passing smoothly, try inserting a metal rod into the hose to remove any particles or metal parts that could be blocking it. Just make sure that you do this slowly to avoid puncturing the hose.

Additionally, check if there are any mesh balls between each inlet valve and the hose as they could be dirty. Clean them thoroughly to avoid obstructing the water flow into the machine.

Clogged Water Inlets

If none of the above steps worked, you can diagnose the water inlets to check if anything is blocking them. You may not be able to see well, so use your smartphone’s flashlight to see inside the inlets.

It’s worth noting that the inlets could be clogged from inside the washing machine. In that case, you’ll have to remove the access panel to inspect the inlets from the inside. The wiring could be on the front or back of the washing machine, depending on the model.

Make sure that the wiring harness is secured to the water inlets. Also, check the solenoid inside the valve for signs of damage.

Blocked Dispenser Drawer

Blocked Dispenser Drawer

Another component that could cause the 4E error code is the dispenser drawer. A blocked dispenser drawer will create issues in the supply of water. Your best bet would be to clean the detergent drawer by following these steps:

  • Open the drawer
  • Push the release level inside the drawer while pulling it outwards
  • Remove the liquid detergent guide and the softener compartment from the drawer
  • Clean all the parts with water
  • Use a hard toothbrush to get rid of the recess inside the drawer
  • Reinstall the liquid detergent guide and the softener compartment and push the drawer inside again

These steps should work for both manual and automatic detergent dispensers in all Samsung washing machines.

Faulty Water Pressure Switch

A malfunctioning pressure switch may cause problems in the washer’s supply system. This is a less common cause of the 4E error code, but it happens. Check the wiring of the pressure switch for damage. If all of them look good, you could try replacing the pressure switch.

Does Unplugging a Samsung Machine Reset It?

Yes, you can reset your Samsung washing machine by simply unplugging the power cord and reconnecting it again.

Just make sure that you wait for a few minutes before plugging back the cord to give the electrical charge enough time to clear out of the washing cycle. Start a new washing program to verify that you’ve reset the machine.

Some newer models come with a reset button that makes the whole process easier.

What If I Fixed the Cause of the 4E Error Code on My Samsung Washing Machine But the Error Message Doesn’t Go Away?

If you’re 100% sure that you’ve fixed whatever is causing the 4E error, but the message is still here, try resetting the washer. It could be due to a glitch in the control board. In some cases, the control module may not be able to detect how much water is provided to the appliance.

Unplugging and replugging the power cord after a couple of minutes will likely fix this problem, but in rare cases, it could mean that it’s time to buy a new control board.


That’s all for this guide! You should now be able to get your Samsung washing machine up and running again after clearing out the 4E error code. Most of the time, you’ll probably find out that something is blocking the supply of water or the drain hose.

Most users should be able to fix the problem on their own, but if you had no luck resolving the issue after trying out everything, contact the repair center for professional help.

On a final note, remember that safety always comes first, so make sure that you turn off the machine before inspecting any components. Also, wear protective gear if needed.
